The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 0.4 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.1 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00005 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.07 SJR: 0.198 SNIP: 0.48 CiteScore™:: 1.1 H-Index: 20

ABSTRAKT

DC plasma technology has been used for many years in the spraying of polymers. However, especially for the low melting point polymers, basic exergy analysis shows that a lot of the high availability energy is wasted in the process. Following exergy analysis, a high energy recovery dc plasma torch has been developed and applied to the deposition of > 10 mm thick polymer composites for abrasion resistant protective surfaces. The injection of low cost fillers such as alumina or silica into the hot plasma zone can absorb much heat and cool the plasma, while the polymer powder is injected into the cooler zone downstream. After deposition, the energy absorbed by the fillers can then be transferred within the polymer matrix coating providing for an energy recovery mechanism. The exergy analysis undertaken for this new process concept shows that the availability of the biphasic plasma/Al2O3 (−22 + 5 µm) fluid increases with build up of alumina particles feed rate which in turn magnifies the useful exergy efficiency. Coating surface roughness measurements show that without alumina particles, the surface is very rough because the presence of unmelted polymer particles. However, the addition of the alumina decreases the roughness due to the hot filler particles completing the polymer melting process inside the coating.
